I understand your point of view, but charging capacitor during the whole day is not a viable option. This is due to the fact that the amount of Joules needed is enormous.

If you think about it, why would'nt we put these capacitor directly into the car... The answer, we can't (yet). The volume would be too big. This means the charging aparatus would be HUGE! hence, you would need a garage for the aparatus itself (plus probably a good amounth of cash). Unless, like you said, if it was at a charging station...

Sorry but your maths are not exactly right!

Watts != Energy
Watts == Power!

Huge difference there. But I do agree that charging batteries for 100 miles/161km in 10 minutes will require a lot of Energy. I'll give it a try...

I read somewhere that a car needs about 30 hp on the highway at 100 km/h (62mph). If that is true, you will need about 22.37 kW for 1.61 hours. This means about 36 kW-hour of energy. Now, back to your house, in order to charge that in 10 minutes, you will need a power output of 216.1 kW. Using 240 Vac, this will result in a current of 900 Amp.

I may be wrong, but 900 Amps is a lot more than what the tipical house can take (200 Amps over here).

Wait, what, no: "Choose two" ?!?

I'm not sure we should start talking about Seagate!!! Latetly, I would'nt buy another drive from them. I guess we will have to wait and see what happens with their new firmware.
